This changes all "Name Surname for CERN" to "Copyright CERN, author
Name Surname". This is trivial and makes no change, with a few
expections:
- all trivial Makefiles that had "for CERN" lines have now no
attributions, as they are trivial anyways.
- a few unrepresented files have not the copyright notice (especially
ptpdump, that I wrote in 2012).
- a few "for CERN" remain in subprojects, where I didn't touch anyrhing
